Isocyano(triphenylphosphoranylidene)acetates: Key to the One-Pot Synthesis of Oxazolo[4,5-c]quinoline Derivatives via a Sequential Ugi/Wittig/aza-Wittig Cyclization Process

The Journal of Organic Chemistry, Год журнала: 2019, Номер 84(22), С. 14911 - 14918

Опубликована: Окт. 17, 2019

A one-pot novel strategy is described for the construction of various oxazolo[4,5-c]quinoline derivatives starting from isocyano(triphenylphosphoranylidene)acetates, aldehydes, amines, and 2-azidobenzoic acids. The reactions generated target products directly in moderate to good yields via a sequential Ugi/Wittig/aza-Wittig cyclization process. salient features method are that all three groups multifunctional isocyanides were involved reaction with broad substituent scopes mild conditions, making protocol useful contribution synthesis heterocycles.

Tandem Phospha‐Michael Addition/N‐Acylation/ Intramolecular Wittig Reaction of aza‐o‐Quinone Methides: Approaches to 2,3‐Disubstituted Indoles

Advanced Synthesis & Catalysis, Год журнала: 2020, Номер 362(13), С. 2615 - 2619

Опубликована: Апрель 30, 2020

Abstract A tandem phospha‐Michael addition/ N ‐acylation/intramolecular Wittig reaction of in situ formed aza‐ o ‐QMs is disclosed. This approach features high functional group tolerance and provides a convenient practical access to biologically significant indole derivatives (37 examples, up 91% yield) under mild conditions. magnified image
